Specification of Letters Patent No. 8,154, dated June 10, 1851.

To all whom it may concern:

Be it known that we, HUGH SANGSTER and JAMES SANGSTER, of the city ofBuffalo, county of Erie, and State of New York, have invented anImproved Mode of Constructing Lanterns, of which the followingdescription, taken in connection Withthe accompanying drawingsandreferences, is sufficiently clearand comprehensive to enable othersof competent skillto make and use our invention: p p

The naturelof our improvement consists in providing thelamp with twosprings, each attached to its upper part (one opposite the other,) andextending down nearly to the base of the lamp, when each forms an elbowthence passing under the lamp and terminating immediatelybelow it, so asto permit the,

lamp to be removed from the lantern with ease and facility by pressinghorizontally upon the springs.

Figure 1, is a semi-perspective view of the whole lantern. Fig. 2 is asemi-perspective vertical section. Fig. 3 isa bottom view lookingupward.

A, is theglass, B, the cap, and C, the ring A i or bail bywhich thelantern is carried. The

glass is set in the case or frame D, Which incloses the lamp F, and theburners H.

This frame or case has a circular flange E,

rest upon the flange and thus secure the,

lamp in this position. Upon" pressing the knobs L toward each other thesprings will be brought in contact with the sides of the rapidity andcase, while it is rendered at the lamp and permit it to be removed withsame time perfectly secure from being accidently disengaged.

What We claim as our invention and .de-

sire to secure by Letters Patent is Themode of attaching the lamp to thelantern by means of the springs andflanges as herein substantially setforth.
